There are three main types of in-ground pools: vinyl, fiberglass, and concrete. Vinyl pools are the most affordable, but they don't last as long as fiberglass or concrete pools. Fiberglass pools are low-maintenance and come in a variety of shapes and sizes, but they can be more expensive than vinyl pools. Concrete pools are the most durable and customizable, but they require more maintenance and can be the most expensive option. Consider your budget, lifestyle, and aesthetic preferences when selecting your pool type. https://skyhighpools.com/best-hard-sided-above-ground-pool/
